NON-REF|LL|NG-STOPPER FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 593,179, dated November 2, 1897. Application filed January 2, 1897. $cria1No. 617,774. No model.)

To all whom it may concern:

Be it known that 1, PETER Lnson, of New York city, in the county and State of New York, have invented a new and Improved Stopper to Prevent Refilling of Vessels, of which the following is a full, clear, and exact description.

My invention relates to a new form of stopper which may be employed with bottles and other vessels having a neck-like opening of the ordinary construction and while permitting the free egress of the contents will automatically close the opening to prevent the insertion of any additional liquid.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical elevation of the stopper within the bottle, the upper end of the bottle being shown in section. Fig. 2 is a vertical section through the bottle and stopper. Fig. 3 is a similar view with theneck of the bottle down, showing the position of the parts when pouring out the contents of the bottle; and Fig. 4 is a horizontal section on the line 44 of Fig. 1.

My device may be applied to bottles, jugs, or any other vessel having a neck-like opening. 1 have herein shown it as applied only to bottles.

vessels. In using my device in connection with such vessels it is not necessary to make any change in the vessels themselves.

The stopper is complete in itself and independent in its operation from the structure of the containing vessels, except that the orifice in the vessel must be round and of the proper size and depth to receive the stopper.

The stopper is in the general form of a circular cone, having an opening in the point of the cone and a valve inside the same,

' which is controlled by a spring and float.

The outer member B of this stopper is made It will, however, readily be seen that it may be as well applied to many other to fit closely in the orifice of the neck A of the bottle or other vessel A to'which it is applied. This stopper is made, preferably, of thin metal and shaped exteriorly as a cone having'a curved outline. At its upper end or point it is provided with a small orifice 1). Within this stopper and below this orifice are two baffle-plates 'B, projecting from opposite sides of the cone and overlapping each other, so as to permit the passage of the liquid but prevent the insertion of a wire within the hole I) to tamper with the valve. The inner or larger end of the cone Bis screw-threaded on its inner surface and receives the valve-seat and spring-casing C, which screws therein.

The upper end of the casing 0 forms a seat for'the valve D, which has a stem 61 extend in ginwardly and connected to a yoke E. The lower end 0 of the casing O is provided with opposite longitudinal slots G, which receive the outer ends of the yoke E and guide the same. Within said casing and resting at one end upon the ledge f and at the other end upon the yoke E is a spirally-coiled spring F, which is made of suificient strength to hold the valve D upon its seat against the pressure of the liquid in the vessel.

Two arms H upon opposite sides of the stopper form a support for the pin C upon which is pivoted the lever G, which upon its outer end has a float I pivoted thereto. This float is made as light as possible, so that it will have very little weight when supported free of the liquid, but will have as great a buoyant effect as possible when immersed in the liquid. The lever G is so shaped that the part on the opposite side of the pivot from the attachment of the float I will engage the yoke when the float is moved toward the interior of the bottle. In the drawings this lever is shown as of a peculiar curved form. It may, however, be made straight or approximately straight. That portion of the lever opposite the attachment of the float being so arranged as to engage the yoke E will depress the same and compress the spring F when the float is immersed in the liquid by inverting the position of the vessel, as shown in Fig. 3. In such a case the buoyant power I the float is immersed in the liquid, the valve of the float I being very much greater than its Weight WiPl have a lifting effect uponthe lever sufficient to depress the opposite end and thus compress the spring and open the valve D. The liquid will then be free to pass out through the opening I) at the top of the portion B of the stopper.

The valve D being normally held down upon its seat by the spring F any liquid poured into the opening of the neck will not have access to the interior of the bottle. The strength of the spring F and the weight of the float I will be so adjusted that the spring will be able to overcome the lifting ,eflect due to the weight of the float and will not permit the float to raise the valve. As this lifting effect is,- however, greater when will be pressed from its seat when the vessel is inverted.

I In utili'zingthe buoyanteffect of the float for opening the valveit makesitim-possible' to have the valve opening with the vessel in any position except when there is suflicient liquid in the vessel to lift the float.

Having thus described my invention, I claim asnew and desiretosecureby Letters Patent- 1, A- closure for vessels,-comprisingaspringclosed valve provided with a valve-stem extendingfrom' its inner side, ayoke on the stem and having guided movement,-a pivoted lever adapted to engage said yoke toforce the valve fromits seat,- and afloat attached to said lever, substantially asdescribed.
